FClose
Declaration:
WORD
FClose
(FILES *
fsPtr
)
Category(ies):
Files
Description:
Close a file. This is required for files opened in WRITE mode. For files in
READ mode just updates the
fsPtr
->fileMode and
fsPtr
->fileStatus fields.
Inputs:
fsPtr
— Pointer to a FILES structure that was previously opened with
FOpen
.
Outputs:
Return FS_OK if file successfully closed. There is extra overhead required
for a FILE that is always kept around by the FILE system and so closing a
FILE will only return an error if the file or the heap has been damaged.
Assumptions:
None
Side Effects:
None
Availability:
On AMS 2.00 and higher.
